visual and auditory centers
✔✔Which theory best explains color vision in humans? - ✔✔Both the opponent-process
theory and the trichromatic theory
✔✔For several nights in a row, a sleep researcher wakes you up whenever you show
signs of entering REM sleep. On the first night that you are allowed to sleep
uninterrupted, you will most likely experience: - ✔✔REM rebound
✔✔The specialized receptor cells for taste are found in the: - ✔✔Taste buds
✔✔The chemical substances that people take to alter mood, thinking, sensation, or
perception are called: - ✔✔Psychoactive drugs
✔✔Sensory receptors for sound are the __________, and they are embedded in the
__________. - ✔✔Hair cells; basilar membrane
✔✔__________ is the most common sleep complaint among adults. - ✔✔Insomnia
✔✔Pain begins when an intense stimulus activated sensory fibers called __________ in
the skin, muscles, or internal organs. - ✔✔Nociceptors
✔✔The __________ of dreaming emphasizes the continuity between walking and
dreaming cognition. - ✔✔Neurocognitive model
✔✔The smallest possible stimulus that can be detected half the time, or the minimum
level of stimulation that we can detect, is called: - ✔✔the absolute threshold
✔✔The tendency to group objects that are close to one another as a single unit is called
the: - ✔✔law of proximity
✔✔According to gate-control theory, psychological, situational, or social factors can
affect the experience of pain because: - ✔✔these factors can cause the brain to send
signals down the spinal cord to either open or close the pain gates
✔✔Shortly after going to bed, as you are falling asleep, you experience the vividly
realistic sensation that you are falling or tripping forward, which jolts you awake. This
vivid sensation is a common example of: - ✔✔a hypnagogic hallucination
, ✔✔As you are reading this question, you are awake and alert. This means that your
brain is generating __________ brain waves. - ✔✔beta

muscles relax and drowsiness occurs. This drowsy yet wakeful state is associated with
__________ brain waves. - ✔✔Alpha
✔✔Long term methamphetamine use can produce damage to the brain's: -
✔✔dopamine system, which is associated with memory and motor skill problems, and
the frontal lobes, which can lead to impairment in cognitive and social skills.
✔✔The three types of neurons are: - ✔✔sensory, motor, and interneurons
✔✔Dr. Rogan calculates a correlation coefficient of -0.72 between the amount of
marijuana smokes and short termed memory capacity. From this correlation coefficient,
Dr. Rogan can conclude that: - ✔✔marijuana consumption and short term memory
capacity are negatively correlated
✔✔A correlation coefficient is a(n): - ✔✔numerical indicator of the strength and direction
of a relationship between two factors
✔✔Researchers at the United Family Therapy Center are conducting a study to
determine how quickly different forms of psychotherapy reduce symptoms of anxiety.
What is the dependent variable in this study? - ✔✔a change in the symptoms of anxiety

two or more variables

the postsynaptic neuron. - ✔✔neurotransmitter; receptor site
✔✔Dr. Harvey calculates a correlation coefficient of +0.68 between the amount of ice
cream sales, and the number of assaults committed during one summer. From this
correlation coefficient, Dr. Harvey can conclude that: - ✔✔ice cream sales and number
of assaults are positively correlated
✔✔Which early school of psychology relied on a method called introspection? -
✔✔Structuralism
